Terms of Service

Gridline BAC™ | Gridline Holdings LLC Effective Date: June 24, 2026 · Last Updated: August 7, 2026

1. Acceptance of Terms

By accessing or placing an order through gridlinebac.com (the "Site"), you agree to be bound by these Terms of Service ("Terms"), including the binding arbitration provision and class action waiver in Section 20. If you do not agree, do not use the Site or place an order. Gridline Holdings LLC ("Gridline BAC," "we," "us," or "our") reserves the right to update these Terms at any time. Continued use of the Site after changes are posted constitutes acceptance of the updated Terms. The version of these Terms in effect at the time you place an order governs that order.

2. Products — Research and Laboratory Use Only

All products sold through this Site are supplied exclusively for laboratory and research use only. They are not intended for human use, animal use, clinical use, diagnostic use, therapeutic use, or consumption of any kind, and are not sold or labeled for any such purpose.

Nothing on this Site — including product descriptions, images, reviews, correspondence, or customer service communications — constitutes medical, veterinary, or other professional advice, and no statement by us or our personnel may be relied upon as such.

3. Buyer Representations and Warranties

By placing an order, you represent and warrant that:

• You are purchasing the product solely for lawful laboratory or research purposes.
• You (or the organization on whose behalf you purchase) possess the knowledge, training, facilities, and qualifications necessary to safely receive, store, handle, and use laboratory materials.
• You have independently determined that the product is suitable for your intended research application, and you are not relying on Gridline Holdings LLC for any such determination.
• You understand and will comply with all applicable federal, state, and local laws and regulations governing the purchase, possession, handling, storage, use, and disposal of laboratory materials.
• You will not use, offer, sell, resell, distribute, or transfer any product purchased from this Site for human use, animal use, or any purpose other than legitimate laboratory or research applications, and you will not remove, alter, or obscure any labeling.
• All information you submit in connection with an order is true, accurate, and complete.

These representations are a condition of sale. Any order placed in violation of them is unauthorized, and any resulting use of the product constitutes misuse for which you bear sole responsibility.

4. Assumption of Risk; Misuse

You assume all risk and liability arising from the receipt, storage, handling, use, misuse, or disposal of any product purchased through the Site. Any use of a product contrary to its labeling, these Terms, or applicable law constitutes misuse. Gridline Holdings LLC shall have no liability of any kind for misuse of any product, including without limitation any personal injury, illness, death, or property damage resulting from human or animal use, injection, or consumption.

5. Eligibility; Verification

You must be at least 18 years of age (or the age of majority in your jurisdiction, if higher) to use this Site or place an order. By placing an order, you represent that you meet this requirement. We do not knowingly sell to minors.

We reserve the right, at our sole discretion and at any time, to require reasonable verification of your identity, age, or intended use, and to refuse, limit, hold, or cancel any order — before or after payment — with a refund of amounts paid for unshipped products as the sole remedy.

6. Orders, Pricing, and Payment

All orders are subject to acceptance and availability. Your order is an offer to purchase; no contract is formed until we dispatch the product. We reserve the right to limit quantities per order, per customer, or per shipping address, and to refuse or cancel orders at any time without prior notice.

Prices are listed in U.S. dollars and are subject to change without notice. We are not responsible for typographical or system pricing errors and reserve the right to cancel any order placed at an incorrect price, with a full refund of amounts paid for that order as the sole remedy.

Payment is due at the time of order. By submitting payment information, you represent that you are authorized to use the payment method provided and that the billing information supplied is accurate.

7. Chargebacks and Payment Disputes

If you believe there is an error with your order or a charge, you agree to contact us first through gridlinebac.com/pages/contact and allow us a reasonable opportunity (not less than 5 business days) to resolve the issue before initiating a payment dispute or chargeback.

We reserve the right to contest any chargeback we reasonably believe to be invalid, including by submitting order records, delivery confirmation, correspondence, and these Terms to the payment processor or card network. Customers who initiate chargebacks that are resolved in our favor, or who we reasonably determine have abused the dispute process, may be refused future orders, and we may pursue recovery of amounts owed, including reasonable costs of collection, to the extent permitted by law.

8. Shipping; Title and Risk of Loss

Orders are processed and shipped according to the timeframe stated on the Site or at checkout. Same-day dispatch applies to orders placed by 2:00 PM ET on business days, subject to availability. Dispatch timeframes are estimates and not guarantees.

We ship within the United States only. Products may not be exported, re-exported, or transferred outside the United States.

Title to products and all risk of loss or damage pass to you upon our delivery of the package to the carrier. Gridline Holdings LLC is not responsible for delays caused by carriers, weather, incorrect shipping information provided by the customer, failed delivery attempts, refused packages, or other events outside our reasonable control, nor for packages that are delayed, lost, stolen, misdelivered, or damaged in transit after handoff to the carrier, except as expressly provided under Shipping Protection (Section 9) if purchased.

Customers are responsible for providing accurate and complete shipping information at checkout and for promptly retrieving delivered packages. Additional shipping charges may apply if an order must be re-routed due to incorrect information. Products are shipped from controlled room temperature storage; we cannot control ambient conditions during transit, and brief ambient temperature exposure during shipping is not a defect.

9. Shipping Protection (Optional Add-On)

Shipping Protection is an optional service offered and administered solely by Gridline Holdings LLC. For the fee stated at checkout, Shipping Protection provides limited protection for qualifying shipping-related loss or damage occurring while an order is in transit.

Shipping Protection is a service commitment provided by Gridline Holdings LLC. It is not an insurance policy and is not underwritten by any third party.

What Shipping Protection Covers

Subject to the requirements and exclusions below, Shipping Protection may cover:

• Packages lost in transit before being marked delivered by the shipping carrier.

• Packages damaged in transit before or during delivery.

• Confirmed carrier misdeliveries, but only when the shipping carrier determines or provides documentation showing that the package was delivered to an address or location other than the shipping address provided on the order.

For an approved Shipping Protection claim, Gridline Holdings LLC will, at its option, either:

• Re-ship the covered order one time; or

• Refund the purchase price of the covered order.

The remedy selected is at the reasonable discretion of Gridline Holdings LLC.

Carrier Claim or Investigation Required

Shipping Protection claims involving a lost, missing, damaged, or allegedly misdelivered package must first go through the applicable shipping carrier's claim, investigation, missing-mail, or service-request process before Gridline Holdings LLC makes a final determination regarding coverage.

Depending on the circumstances, Gridline Holdings LLC may require the customer to contact USPS, UPS, or another applicable carrier and provide information necessary for the carrier to investigate the shipment.

Customers may be required to provide:

• A carrier claim number;

• Service request or investigation number;

• Missing Mail Search number;

• Written or electronic correspondence from the carrier;

• Carrier confirmation regarding the delivery location;

• Photographs of damaged products and packaging; or

• Any other documentation reasonably necessary to determine what occurred.

Gridline Holdings LLC may also open, participate in, or communicate with the carrier regarding a claim or investigation.

The filing of a carrier claim does not automatically qualify an order for a refund or replacement.

Gridline Holdings LLC will not make a final Shipping Protection determination until the applicable carrier investigation has been completed, closed, denied, or otherwise progressed to a point where sufficient information is available to reasonably determine what occurred.

Customers must reasonably cooperate with the investigation and provide requested information. Failure to provide requested documentation or cooperate with the carrier investigation may result in denial of the Shipping Protection claim.

Packages Marked Delivered

Shipping Protection coverage ends once the shipping carrier marks the package as “Delivered,” except where the carrier subsequently confirms that the package was misdelivered to an incorrect address or location.

A package marked Delivered by the carrier is considered successfully delivered for purposes of Shipping Protection.

Shipping Protection does not cover a package solely because the customer reports that they did not personally receive, see, retrieve, or locate the package after the carrier marked it Delivered.

This includes packages reported missing from or after delivery to a:

• Mailbox;

• Porch or front door;

• Parcel locker;

• Mailroom;

• Reception or front desk;

• Apartment or condominium delivery area;

• Business delivery area; or

• Other location at or associated with the shipping address.

Shipping Protection also does not cover packages that are:

• Stolen after delivery;

• Removed from the delivery location after delivery;

• Misplaced after delivery;

• Received or retrieved by another household member;

• Received by a roommate, family member, neighbor, receptionist, building employee, mailroom employee, or other person at or associated with the delivery location;

• Placed by the carrier in an alternate location at the correct delivery address; or

• Otherwise unavailable after a carrier-confirmed delivery.

A customer's statement that a package was not received or cannot be located does not, by itself, establish that the package was lost or misdelivered and does not qualify the order for Shipping Protection coverage.

Exception for Confirmed Misdelivery

If tracking shows Delivered but the customer believes the carrier delivered the package to the wrong address, the customer must first contact the shipping carrier and request an investigation.

The customer must provide Gridline Holdings LLC with the applicable claim, case, service-request, or investigation number when requested.

A Delivered package may be considered for Shipping Protection only if the carrier subsequently confirms or provides sufficient documentation establishing that the package was delivered to an address or location other than the shipping address provided on the order.

If the carrier confirms delivery to the correct address or is unable to substantiate a misdelivery, the package is not covered under Shipping Protection.

What Shipping Protection Does Not Cover

Shipping Protection does not cover:

• Packages marked Delivered to the correct shipping address;

• Packages reported missing after confirmed delivery;

• Theft occurring after delivery;

• Packages misplaced or removed after delivery;

• Incorrect, incomplete, invalid, or undeliverable addresses entered by the customer;

• Delivery to an address entered incorrectly by the customer;

• Refused packages;

• Packages not timely retrieved from a post office, carrier facility, parcel locker, mailroom, access point, or other pickup location;

• Failed delivery attempts caused by an inability to access the customer's delivery location;

• Packages returned because the customer failed to retrieve or accept delivery;

• Customer requests to change the delivery address after shipment where the carrier cannot successfully complete the change;

• Damage occurring after delivery;

• Loss occurring after delivery;

• Claims based solely on a customer's statement that a Delivered package cannot be located; or

• Any circumstance outside the specific covered events described in this Section.

Filing a Shipping Protection Claim

To request Shipping Protection coverage, contact Gridline Holdings LLC through gridlinebac.com/pages/contact within 14 days of the last carrier tracking update or scheduled delivery date, as applicable.

The claim must include:

• The customer's order number;

• A description of the shipping issue;

• Any carrier claim, case, investigation, or service-request number requested by Gridline Holdings LLC; and

• For damage claims, clear photographs of the product, shipping container, packaging, shipping label, and visible damage.

Additional documentation may be requested when reasonably necessary to evaluate the claim.

Claims submitted outside the applicable claim period may be denied.

Claim Review and Resolution

All Shipping Protection claims are reviewed in good faith based on the available tracking information, carrier records, customer-provided documentation, and the results of any applicable carrier investigation.

Gridline Holdings LLC reserves the right to verify information directly with the shipping carrier before approving a claim.

Shipping Protection does not guarantee that every claim will result in a refund or replacement. Coverage applies only when the circumstances satisfy the requirements of this Section.

If a qualifying claim is approved, Gridline Holdings LLC will, at its option, provide either one replacement shipment or a refund of the covered order's purchase price.

Orders Without Shipping Protection

If Shipping Protection was not purchased at checkout, the provisions of Section 8 apply.

Unless otherwise required by applicable law, title and risk of loss transfer to the customer when Gridline Holdings LLC delivers the package to the shipping carrier, and Gridline Holdings LLC is not responsible for loss, theft, misdelivery, damage, or other shipping-related events occurring after carrier handoff.

10. Returns and Refunds — All Sales Final

Due to the controlled nature of laboratory-use materials, all sales are final. We do not accept returns after products have left our possession: storage conditions, temperature exposure, handling, and chain-of-custody cannot be verified once a product has been delivered, and returned goods cannot be restocked or resold.

If a product arrives damaged, incorrect, or missing due to a fulfillment error, contact us through gridlinebac.com/pages/contact within 7 days of delivery, including your order number, photos of the item and packaging, and a description of the issue. We will respond within 1 business day. Refunds or replacements for fulfillment errors are issued at the sole discretion of Gridline Holdings LLC after review of the submitted documentation, and constitute your sole and exclusive remedy.

11. Order Changes and Cancellations

Because orders are processed rapidly for same-day dispatch, cancellation or modification requests can be honored only if received before the order is dispatched. Once tracking has been generated, the order cannot be cancelled and Section 10 applies.

12. Prohibited Uses

You agree not to use the Site or any product purchased through it to:

• Purchase, use, resell, or distribute products for human use, animal use, or any use other than lawful laboratory or research purposes.
• Violate any applicable federal, state, or local law or regulation.
• Export or transfer products outside the United States.
• Submit false, misleading, or fraudulent information, including false identities, payment information, or delivery claims.
• Purchase products on behalf of a third party who could not lawfully make the purchase directly.
• Attempt to gain unauthorized access to any part of the Site or its systems, scrape the Site, or engage in any conduct that could damage, disable, or impair the Site.

We reserve the right to refuse service, cancel orders, and terminate accounts for violations of this Section, and to report suspected unlawful activity to appropriate authorities.

13. Disclaimer of Warranties

THE SITE AND ALL PRODUCTS ARE PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, OR NON-INFRINGEMENT, ALL OF WHICH ARE EXPRESSLY DISCLAIMED TO THE FULLEST EXTENT PERMITTED BY LAW. WITHOUT LIMITING THE FOREGOING, WE MAKE NO WARRANTY THAT ANY PRODUCT IS SUITABLE FOR ANY PARTICULAR RESEARCH APPLICATION; DETERMINING SUITABILITY IS SOLELY YOUR RESPONSIBILITY.

We do not warrant that the Site will be uninterrupted, error-free, or free of viruses or other harmful components, and we make no representations or warranties regarding the accuracy or completeness of any content on the Site. No oral or written information provided by us creates any warranty.

14. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, GRIDLINE HOLDINGS LLC, ITS OWNERS, MEMBERS, OFFICERS, EMPLOYEES, CONTRACTORS, AGENTS, AND AFFILIATES SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF THE SITE OR ANY PRODUCTS PURCHASED THROUGH THE SITE — INCLUDING BUT NOT LIMITED TO PERSONAL INJURY, ILLNESS, DEATH, PROPERTY DAMAGE, LOSS OF DATA, OR LOSS OF REVENUE — EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY FOR ANY AND ALL CLAIMS ARISING OUT OF OR RELATING TO THESE TERMS, THE SITE, OR ANY PRODUCT SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE ORDER GIVING RISE TO THE CLAIM.

ANY CLAIM ARISING OUT OF OR RELATING TO THESE TERMS, THE SITE, OR ANY PRODUCT MUST BE BROUGHT WITHIN ONE (1) YEAR AFTER THE CLAIM ACCRUES, OR IT IS PERMANENTLY BARRED.

Some jurisdictions do not allow certain limitations; in such jurisdictions these limitations apply to the fullest extent permitted.

15. Indemnification

You agree to indemnify, defend, and hold harmless Gridline Holdings LLC, its owners, members, officers, employees, contractors, agents, and affiliates from and against any and all claims, liabilities, damages, losses, costs, and expenses — including reasonable attorneys' fees — arising out of or in any way connected with: (a) your use of the Site; (b) your purchase, storage, handling, use, or misuse of any product, including any human or animal use contrary to labeling and these Terms; (c) your breach of any representation, warranty, or provision of these Terms; (d) your violation of any law or the rights of any third party; or (e) any claim brought by a third party arising from products you purchased, transferred, or supplied to them.

16. Intellectual Property

All content on this Site — including the Gridline BAC™ name, logo, product descriptions, images, and text — is the property of Gridline Holdings LLC or its licensors and is protected by applicable intellectual property laws. You may not reproduce, distribute, or use any content from this Site without our prior written permission. Third-party trademarks (including manufacturer brand names) are the property of their respective owners; their use on this Site is for product identification only and does not imply affiliation, sponsorship, or endorsement.

17. Third-Party Links

The Site may contain links to third-party websites for reference only. We have no control over the content or practices of third-party sites and assume no responsibility for them. Linking does not constitute endorsement.

18. Privacy; Electronic Communications

Your use of the Site is also governed by our Privacy Policy, which is incorporated into these Terms by reference. By using the Site, you consent to our data practices as described in our Privacy Policy.

By providing your email address or phone number, you consent to receive transactional communications about your orders electronically, and, where you have opted in, marketing communications, which you may opt out of at any time. You agree that electronic communications, records, and signatures satisfy any legal requirement that a communication be in writing.

19. Force Majeure

We shall not be liable for any failure or delay in performance caused by circumstances beyond our reasonable control, including acts of God, weather events, carrier disruptions, supplier or manufacturer shortages, labor disputes, epidemics, government actions, payment network disruptions, utility or internet failures, or civil unrest.

20. Governing Law; Binding Arbitration; Class Action Waiver

PLEASE READ THIS SECTION CAREFULLY — IT AFFECTS YOUR LEGAL RIGHTS.

These Terms are governed by and construed in accordance with the laws of the State of Tennessee, without regard to its conflict of law provisions, and, where applicable, the Federal Arbitration Act.

Informal Resolution. Before initiating any formal proceeding, you agree to first contact us through gridlinebac.com/pages/contact and attempt in good faith to resolve the dispute informally for at least 30 days.

Binding Arbitration. Any dispute, claim, or controversy arising out of or relating to these Terms, the Site, or any product purchased through the Site that cannot be resolved informally shall be resolved by final and binding individual arbitration administered by the American Arbitration Association ("AAA") under its Consumer Arbitration Rules. The arbitration shall be conducted in Hamilton County, Tennessee, or, at your election, by videoconference or telephone. Judgment on the award may be entered in any court of competent jurisdiction. The arbitrator, and not any court, shall have exclusive authority to resolve any dispute relating to the interpretation, applicability, or enforceability of this arbitration agreement.

Class Action Waiver. ALL DISPUTES SHALL BE ARBITRATED OR LITIGATED ONLY ON AN INDIVIDUAL BASIS. YOU AND GRIDLINE HOLDINGS LLC EACH WAIVE ANY RIGHT TO PARTICIPATE IN A CLASS ACTION, CLASS-WIDE ARBITRATION, OR REPRESENTATIVE PROCEEDING, AND WAIVE ANY RIGHT TO A TRIAL BY JURY.

Small Claims Exception. Either party may bring an individual claim in small claims court in Hamilton County, Tennessee (or, for consumers, the small claims court of your county of residence) instead of arbitration, for claims within that court's jurisdiction.

Opt-Out. You may opt out of this arbitration agreement by sending written notice through gridlinebac.com/pages/contact within 30 days of your first purchase, stating your name, order number, and intent to opt out. Opting out does not affect any other provision of these Terms.

For any matter not subject to arbitration, you consent to the exclusive jurisdiction and venue of the state and federal courts located in Hamilton County, Tennessee.

21. Severability

If any provision of these Terms is found to be invalid or unenforceable, that provision shall be modified to the minimum extent necessary to make it enforceable, and the remaining provisions shall remain in full force and effect. If the Class Action Waiver in Section 20 is found unenforceable as to a particular claim, then that claim (and only that claim) shall proceed in court rather than arbitration.

22. Assignment; Waiver; Survival

We may assign these Terms in connection with a merger, acquisition, or sale of assets. You may not assign these Terms or any order without our written consent. Our failure to enforce any provision is not a waiver of the right to enforce it later. Sections 2–4, 7–10, and 13–21 survive completion of any order and any termination of these Terms.

23. Entire Agreement

These Terms, together with our Privacy Policy, Refund Policy, and Shipping Policy, constitute the entire agreement between you and Gridline Holdings LLC with respect to your use of the Site and supersede all prior agreements and understandings. In the event of a conflict between these Terms and any other policy, these Terms control with respect to the subject matter of the conflict.
